Hi @davidnadeau , from the backtrce, should be that `classLoaderLocal.get()`
got the null `ClassLoader`
```java
// org.apache.fury.pool.FuryPooledObjectFactory
public ClassLoaderFuryPooled getPooledCache() {
try {
ClassLoader classLoader = classLoaderLocal.get();
ClassLoaderFuryPooled classLoaderFuryPooled =
classLoaderFuryPooledCache.getIfPresent(classLoader);
if (classLoaderFuryPooled == null) {
// double check cache
return getOrAddCache(classLoader);
}
return classLoaderFuryPooled;
} catch (Exception e) {
LOG.error(e.getMessage(), e);
throw new RuntimeException(e);
}
}
```
The `ClassLoader` obtained from the `classLoaderLocal` initialization
function is null
```java
// org.apache.fury.pool.FuryPooledObjectFactory
private final ThreadLocal<ClassLoader> classLoaderLocal =
ThreadLocal.withInitial(() ->
Thread.currentThread().getContextClassLoader());
```
`Thread#getContextClassLoader` seems to be a focus of analysis.
